10. Reliability prediction for structures under cyclic loads and recurring inspections
Abstract: This work presents a methodology for determining the reliability of fracture control plans for structures subjected to cyclic loads. It considers the variability of the parameters involved in the problem, such as initial flaw and crack growth curve. The probability of detection (POD) curve of the field non-destructive inspection method and the cond

11. VOLTAGE STABILITY PROBABILISTIC ASSESSMENT IN COMPOSITE GENERATION AND TRANSMISSION SYSTEMS / ANÁLISE PROBABILÍSTICA DA ESTABILIDADE DE TENSÃO EM SISTEMAS COMPOSTOS DE GERAÇÃO E TRANSMISSÃO
In some countries, the electric power systems are operating near to their limits due to the absence of investments in the transmission network expansion and natural growth of the electricity demand. This operation condition can also occur in electric power systems in which the transmission expansion is carried out in appropriate way. In this case, the excess
